"Talk less. Smile more. Don't let them know what you're against or what you're for."

In the musical, this is Aaron Burr's advice to the young Alexander Hamilton. Later Hamilton replies:

"If you stand for nothing, Burr, what'll you fall for?"

These two quotes epitomize the portrayal of Aaron Burr in the musical Hamilton: he avoids giving his opinions, especially on issues of any controversy, lest it hurt his popularity and thus his career. He's in politics not because he cares about the issues but because he cares about his career and the ego boost he gets from having power.

However, according to Aaron Burr's Wikipedia page:

As a New York Assemblyman in 1785, Burr supported a bill to end slavery

and

Not only did Burr advocate education for women, upon his election to the New York State Legislature, he submitted a bill, which failed to pass, that would have allowed women to vote.

This suggests that Aaron Burr was not shy of controversy, as slavery abolition and women's suffrage were highly controversial issues.

These are just two examples, though, and perhaps they are anomalies. I may also be missing context that would change how these examples should be interpreted.

For those who are informed on the subject, what is your opinion on the portrayal of Aaron Burr?
